HEAT TREATED.
TO SHARPEN BLADE
NOTE: We do not recommend sharpening
blade - but if you do, be sure the blade is
balanced.
Care should be taken to keep the blade
balanced. An unbalanced blade will cause
eventual damage to lawn mower or
engine.
The blade can be sharpened with a file
or on a grinding wheel. Do not attempt
to sharpen while on the mower.
To check blade balance, drive a nail into
a beam or wall. Leave about one inch of
the straight nail exposed. Place center
hole of.blade over the head of the nail.
If blade is balanced, it should remain in
a horizontal position. If either end of the
blade moves downward, sharpen the
heavy end until the blade is balanced.
